Sorry, there must be already an answer, yet I cannot find it.
Can anyone please give me a hint how I can install the old IDE0022 on WIN7 (or XP) for an ARDUINO UNO? There are several posts, no one worked for me. I need 0022 because someone programmed an interface to another machine I will have to use on my arduino because new IDEs will not be compatible.
Since there is no .exe for the old IDE, I tried to unzip the IDE-folder on C:\ and then install the drivers manually by device manager. No way to connect to the UNO.
Does someone know a working way?
